2. Release overview

2.1. Operating system support

See Table 4.3 for details of the operating systems supported.

PyTorch is no longer supported on Debian 10. This change enables the Poplar SDK to support PyTorch version 2.0.1.

Added support for many more layers and operations, including aggregation operations and normalisation layers.
Added functionality to catch layers and operators that use dynamic shapes, switching them for a static alternative or raising to the user if not.
Increased support for heterogeneous graphs.
Improvements to the fixed size data loaders:
- They are now drop in replacements for their upstream counterparts, for example poptorch_geometric.FixedSizeDataLoader is now a “drop-in” replacement for torch_geometric.DataLoader.
- Extended support for heterogeneous data loading.
- Added poptorch_geometric.FixedSizeNeighborLoader.

Compatible with PyTorch 2.0.1 (upgraded from 1.13.1)

Added support for additional torch operations, mostly to enable support for additional PopTorch Geometric layers and operations.
